A Scientific Piano Tuning Instrument

When I say A Scientific Instrument, you may think of something complicated and hard to use. In the case of the ACCU-TUNE there are no complications other than pushing a button for registering the note you are working with. A series of lights rises or descends showing sharpness or flatness, you adjust the pins until the lights stand still. But the instrument "hears" the sounds in a different mode from what you hear. A magnetic pickup is placed directly above each string, while the adjacent strings are damped with the rubber tuner's wedge. The instrument does not read sound, which is a complicated set of relationships between string, bridge, soundboard, and the room. It reads the vibrating motion of the string, and tunes the string to a given, correct frequency, stretching high and low notes mathematically on a precise set of curves.

This system has the exact frequencies to four decimal places encoded in its memory chip, it compares the reading from each string with the numbers in memory, and signals with the light sequence as you approach the theoretically correct number. That's all there is to it.

This permits you to make all the string adjustments in relation to an exact mathematical model of great accuracy, you can tune one string, or the whole piano one note at a time in this uncomplicated manner. There are no learning curves like those which a tuner has had to deal with, no practice tuning a hundred pianos until you are skilled enough to qualify. It is true, the tuner can do the job in an hour if he is fast, he can do it very well if he is skilled. But not every tuner does the same work, some are better and some less good, whereas if you tune with the ACCU-TUNE and the lights flash in the right order, the work is done right. It will be slower than the tuner's job, but you gain by being able to do checkups when needed, and in a few years you have recovered the cost of the instrument. I consider this saving of cost the least significant factor, far more important is having your piano always in tune, and learning to really listen to sounds with refocused attention and enjoyment.
